,Zfo all ztfhom it may concern: I, Be t known that I, CHARLES HoUsEMAN, a {CltlZCll of the Republic of France, and resident. of Rochester, in the county of Monroe andState of New York, have invented certainnew and useful Improvements in Printing-Machines, of which the following is a specification.

-- The. present invention relates to printing machines, and more particularly to the type in which means is provided for rupturing or breaking the paper iii such a way that the changing of the matter printed is rendered ing machine which is not limited to any certa navords or expressions but is capable produc ng any written instrument or document, protected to render difficult the .sdchanging' ofthe instrument or document.

Still encamobje'ct of the invention is to provide, in an ordinary typewriting machine, a rupturing means which will rupture or break the paper on either or both sides of the printing point. A further object of the invention is to combine with a printing ina- "chine having an inkii'ig ribbon, a rupturing iiiea'n's which will rupture the paper or-Work without injury to the inking ribbon. A still further object of the invention is to provide a rupturing means combined with a platen and printingmechanism and controlled by the latter.

To these and other ends the invention consists of certain parts and "combinations of parts, all of which will be hereinafter described, thenovel features being pointed out v in the appended claims. In'the drawings Figure 1 is a front view of a typewriting machine embodying the present invention; Fig. 2 is a detail view of the line guide of "the machine illustrated in Fig. 1, showing one embodiment of the rupturing means associated with said guide;

Fig. 9 is an enlarged detail View of another embodiment iii which the rupturing means ruptures the paper on both sides of the printing point.

The invention is herein illustrated as embodied in a printing machine of the type known as a typewriting machine, in which the type are selectively moved to the printing point and a roller platen is employed for supporting the work and receiving the impact of the type, the platen being lied step-by-step in th direction of the printing line for producing the letter spacing and being rotatable about its longitudinal axis to produce line spacing, a suitable inking ribbon being employed and mounted in front of the platen so that the type will strike the ribbon and produce an impression on the work arranged between the ribbon and tl're platen. Typewriting machines of this type are so well known that further description and illustration of their inechanismsis unnecessary, the specific machine herein illustrated being known to the trade as the Corona. It is apparent, however, that the invention is not limited to the use with a typebar typewriting machine, but may .be employed in connection with any printing machine in which a platen or its equivalent is engaged by a printing mechanism of. any construction.

Referring now to the drawings ofl the illustrated embodiment of the invention,- 1 indicates a roller platen having a rubber or yielding surface, 2 a type barof the printing mechanism which is controlled by the keys 3 of a keyboard. The inking mechanism has an inking ribbon 4 which is :40 Y position it 'maybe removed from the ma-' mounted on spools Sin front of the platen 1- I to be engaged by the :type 6 on the type fhead'l. ,Thelplateri, as before 'stated,-ha'sarotar'y movement for/line spacing. and a step-by-step "movement in the direction of itsjlength. for letter spacing, as is common in machines oflthis type {A line guideS is arranged in front. of, the; platen and the ewhieh the type barsjst'rike.

ribbon 4 lies in v front of the guide, the, guide bei 'gprovided with an opening 9 throughv The rupturing means is, this-instance, in'the': form of-a plate 10 with "an opening- :11. therein,-' through whichthe type 6 are 1 adapted to pass. "In the embodiment shown "in Figs. "1 to 85 projections 12am extended from one side oi the opening andfh'avethei-n free ends formedinto knifeed'gesliv, while in the embodimentshown'in Fig. 9 two se- .ries of. projections 12 are provided; one Ton each side of the opening 11, and each proj ec- *tion havin a knife edge 13 at its rear end.

The plate'I'O has a resilient'p'ortion 14 con- .f'nected with an att ng PQ r tachin'g portion being securedfto the line guideBat-one sideof. the opening'9 so that fthejopening 10 of the rupturing device with the rupturing. projections. 12 lie over the opening. 93in. the. line gu'ide. In this instance, theglineguide' has: two headed pro jction's'lGQand the attaching portion '15 has .two slots' 17 fand 18, .the'latter being curved t olt.

and opening at thefunder side of; the a't -f taching portion, while. the slot-17. is straight and opens at the end: of the 'attachin'gpop This arrangement permits the rup turing device to-beswung from'th'e. poslt on shown in Fig.2. over the opening 9 'of'the line. guide. until it occupies.. ;theposition shown; indotted: lines i'nFig; 2, in which I chine. f This mounting of the rupturing I'neanspermits I the "latter 'to' be thrown into use at will, or tobe'. moved to fill lIlOPQI'EL- v 46 I In he-operation of the invent on, when tive' position when notf'desired;

it is desired to rupture the paper; the rup-- turing means; is 'thrownto the position 5 shown in thefullfiline in-Fig 2, and the Ito-p netrate thepaper at. onejsidehof the printing point, according to the embodiment shown'm Figs. 1 to 75.01". on both sidesacwardthe platen-and causes said projections cording to the embodiment shown in ,Fig 9.

When the type h'ead17 strikes. the plat-e10 thelatter yields .at the point 14 so'that, When- ,the. type head moves away from thedevice, the latter will assume its original position and the movement of theplatenis'hot inter-- area withl When only one set of; mp'tulf length of the cutting edgesiof the-projeo' not only is the paperrupturedat-the vpre-' gceding letter, but'it also isruptured at a.

' paper oceurs'simultaneously with the print 1 nism and is arranged between the ribbon of ing projections is employed, as shown in Figs. 1 to 7,. the paper. will be cut in horiz'ontallines, as shown inFig. '8, thelen'gth of 'these cuts; of course, depending upon the tionsk. At thebsame time the cuts-' .'are made-2K letter is printed, for example, when the letter H 'ofFig. 8 is, printed, the sl ts'19on" the letter will be formed,-while the slits" on the letter H will. be formed when the letter I is. struck. It is apparent that asone letter is struck almost immediately 1 after the one preceding it, theink onthe'preeed- .i'ng letter will not. be dry, {so that as the' paper is cut the ink will behfo'rced into the rupture. rIn theembodiment shownin Fig,

9, as each'lett-er'is struck-a rupture-d por tion is providedon oppositesides' thereof; so that Withthe printing of any one letter" point where a letter is to be "subsequently imprinted. In this way most ofthe letterswill be imprinted upon a surface which has previously been ruptured and afterv being suring thebre'aki-ng up of the paper.

. From-the foregoingit will be seenthat there has been provided arrupturing jineans" .combined' witha printing mechanism in such a .manner that any. written instrument.

or document can be protected against surf: 1 reptitious changing. The 'rup'turing oi" the .100 ing a'ction in. an area'to one or both sides of the printing. area or point. "The-rupturing means is operated by the printing meeha-- the inking mechanism and the platen 'soth-at 1 the ribbon'is not afi'ected'by-the rupturing -means. 'In the illustrated embodiment',' the. invention is carried outby attaching a rupturing. device. to .an ordinary typebarftype v writing machine so that the latter maybef =used'with or without the rupturing devicex What-I claim as my invention and desire 'to secure by Letters Patent is.
